Calculate resistance of power through 12 ohm is 36 watt
Answers
Ohm's law formula
The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω):
V(V) = I(A) × R(Ω)
The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A):
P(W) = V(V) × I(A)
AC Ohm's law formula
The voltage V in volts (V) is eqaul to the current I in amps (A) times the impedance Z in ohms (Ω):
V(V) = I(A) × Z(Ω) = (|I|×|Z|) ∠ (θI + θZ)
The complex power S in volt-amps (VA) is equal to the voltage V in volts (V) times the current I in amps (A):
S(VA) = V(V) × I(A) = (|V|×|I|) ∠ (θV - θI)

Enter any two known values and press "Calculate" to solve for the others. For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps. Enter 100 in the Watts field and 120 in the Voltage field and press Calculate to find the resistance and current. Fields should be reset to 0 before each new calculation.
Voltage (E) = Current (I) * Resistance (R)
Power (watts) = Current Squared (I^2) * Resistance (R)
Power = I*E = E^2 / R
